NR509 Advanced Physical Assessment Week 7
OSCE Exam Questions & Clinical Scenarios
Comprehensive Practice Examination – 130
Questions with Answers and Rationales
1. A 45-year-old male presents with a 3-day history of sharp, stabbing chest pain that worsens with
deep inspiration and is relieved by leaning forward. Which of the following is the most likely
diagnosis?
A) Myocardial infarction
B) Pericarditis
C) Pneumothorax
D) Pulmonary embolism
Correct Answer: B) Pericarditis
Rationale: Pericarditis classically presents with sharp, pleuritic chest pain that worsens with
inspiration and is relieved by leaning forward (a pathognomonic feature). Myocardial infarction
typically presents with pressure-like pain that radiates to the arm or jaw and is not relieved by
positional changes. Pneumothorax presents with sudden-onset dyspnea and absent breath
sounds. Pulmonary embolism presents with pleuritic pain but is not typically relieved by leaning
forward.
2. During auscultation of the heart, a mid-diastolic rumble heard at the apex with the bell of the
stethoscope is most consistent with:
A) Aortic stenosis
B) Mitral stenosis
C) Mitral regurgitation
D) Aortic regurgitation
Correct Answer: B) Mitral stenosis
Rationale: Mitral stenosis produces a low-pitched mid-diastolic rumble best heard at the apex
with the bell of the stethoscope while the patient is in the left lateral decubitus position. Aortic
stenosis produces a crescendo-decrescendo systolic murmur at the right second intercostal
space. Mitral regurgitation produces a holosystolic murmur at the apex radiating to the axilla.
Aortic regurgitation produces an early diastolic decrescendo murmur at the left sternal border.
,3. A patient presents with a blood pressure of 150/95 mmHg in the right arm and 120/80 mmHg in the
left arm. This finding is most suggestive of:
A) Normal variation
B) Aortic dissection
C) Subclavian steal syndrome
D) Coarctation of the aorta
Correct Answer: D) Coarctation of the aorta
Rationale: A systolic blood pressure difference of greater than 20 mmHg between arms is
abnormal and suggests coarctation of the aorta or subclavian stenosis. Coarctation of the aorta
classically presents with upper extremity hypertension and lower extremity hypotension, often
with a blood pressure differential between arms. Aortic dissection typically presents with
abrupt, severe tearing pain and pulse deficits. Subclavian steal syndrome causes arm
claudication with exercise.
4. Which of the following is the most sensitive physical examination finding for detecting early
congestive heart failure?
A) Peripheral edema
B) Jugular venous distention
C) S3 gallop
D) Crackles on auscultation
Correct Answer: C) S3 gallop
Rationale: An S3 gallop is one of the earliest and most sensitive indicators of elevated left
ventricular filling pressures and systolic dysfunction in heart failure. It is caused by rapid
ventricular filling during early diastole. Peripheral edema and JVD are signs of right-sided heart
failure and may appear later. Crackles indicate pulmonary congestion but may be absent in
chronic heart failure due to lymphatic compensation.
5. A 62-year-old smoker presents with a chronic cough and is found to have clubbing of the fingers.
Which of the following is the most likely underlying condition?
A) Chronic obstructive pulmonary disease
B) Lung cancer
C) Tuberculosis
D) Asthma
Correct Answer: B) Lung cancer
,Rationale: Digital clubbing is most commonly associated with lung cancer (especially non-small
cell lung cancer) and other conditions causing chronic hypoxia, such as bronchiectasis, cystic
fibrosis, and interstitial lung disease. While COPD can cause chronic hypoxemia, clubbing is not
a typical feature. Tuberculosis and asthma do not typically cause clubbing.
6. On examination of the abdomen, you note a bruit in the epigastric region. This finding is most
suggestive of:
A) Abdominal aortic aneurysm
B) Renal artery stenosis
C) Pancreatic tumor
D) Gastric ulcer
Correct Answer: B) Renal artery stenosis
Rationale: An epigastric bruit is most commonly associated with renal artery stenosis,
particularly when heard in the epigastrium or flank. It can also be heard with abdominal aortic
aneurysm, but a bruit alone without a pulsatile mass is more suggestive of renal artery stenosis.
Pancreatic tumors and gastric ulcers do not typically produce bruits.
7. Which of the following is the correct technique for assessing the apical pulse in an adult?
A) Place the diaphragm at the left fifth intercostal space, midclavicular line
B) Place the bell at the left fifth intercostal space, midclavicular line
C) Place the diaphragm at the left fourth intercostal space, sternal border
D) Place the bell at the right second intercostal space
Correct Answer: B) Place the bell at the left fifth intercostal space, midclavicular line
Rationale: The apical pulse (point of maximal impulse) is best auscultated with the bell of the
stethoscope at the left fifth intercostal space at the midclavicular line. The bell is used because it
detects low-frequency sounds. The diaphragm is used for high-frequency sounds like murmurs.
The right second intercostal space is the aortic area.
8. A patient presents with sudden-onset severe headache, neck stiffness, and photophobia. Which of
the following is the most likely diagnosis?
A) Migraine headache
B) Tension headache
C) Subarachnoid hemorrhage
D) Cluster headache
Correct Answer: C) Subarachnoid hemorrhage
, Rationale: The classic triad of sudden-onset severe headache ("thunderclap headache"), neck
stiffness, and photophobia is highly suggestive of subarachnoid hemorrhage. Migraine
headaches are typically unilateral, pulsating, and associated with nausea and aura. Tension
headaches are bilateral and pressing. Cluster headaches are unilateral, periorbital, and
associated with autonomic symptoms.
9. During a neurological examination, a patient is unable to identify a familiar object placed in their
hand without looking at it. This finding is known as:
A) Anosognosia
B) Astereognosis
C) Agraphesthesia
D) Apraxia
Correct Answer: B) Astereognosis
Rationale: Astereognosis is the inability to identify objects by touch alone without visual cues,
indicating a lesion in the somatosensory cortex (parietal lobe). Anosognosia is denial of illness.
Agraphesthesia is the inability to recognize numbers or letters traced on the skin. Apraxia is the
inability to perform learned motor tasks despite intact motor function.
10. A patient presents with a resting tremor that improves with intentional movement, cogwheel
rigidity, and bradykinesia. Which of the following is the most likely diagnosis?
A) Essential tremor
B) Parkinson's disease
C) Huntington's disease
D) Cerebellar ataxia
Correct Answer: B) Parkinson's disease
Rationale: The classic triad of Parkinson's disease includes resting tremor (pill-rolling), cogwheel
rigidity, and bradykinesia. Essential tremor is an action tremor that worsens with movement
and is often familial. Huntington's disease presents with chorea and cognitive decline. Cerebellar
ataxia presents with intention tremor, dysmetria, and ataxia.
11. Which of the following findings is most consistent with a diagnosis of acute otitis media on
otoscopic examination?
A) Pearly gray, translucent tympanic membrane
B) Bulging, erythematous tympanic membrane with decreased mobility
C) Retracted tympanic membrane with visible bony landmarks
D) Perforated tympanic membrane with purulent drainage
